Really? I thought 9 was 3 squared.

Are these cooling programs useful when used together with prime95? I guess it wouldnt work because the cooling programs run only at the minimum priority and then they would "fight" idle time with prime95 (which is also by default set to work only in idle time), but maybe cooling programs and prime95 work well together. I dont know... Does anyone have the answer to this question? Did someone already tested it some time? Please tell me what you've got.

Windows NT and Linux does this, I think Win95 does as well, Windows 3 and DOS do not. Since the purpose of Prime95 is to use as much of the CPU time as can be spared by other processes, it works extremely bad with the concept of saving power by halting the processor, because the optimal working conditions for Prime95 is to run flat out using the entier processor all the time. - -- Henrik Olsen, Dawn Solutions I/S URL=http://www.iaeste.dk/~henrik/ Speak of the Devil and he will hear about it.

Win95 doesn't, theres a program "CPUIdle" to add that feature. It runs at idle priority and HLTs the CPU when it gets its time slice. DOS sure doesnt as it has no multitasking concept, though maybe you could add a HLT to the INT 21-routines that wait for keystrokes etc. Ciao, Alex. _________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers ------------------------------ Date: Wed, 17 May 2000 09:57:04 +0200 (MET DST) From: "Benny.VanHoudt" <[EMAIL PROTECTED]> Subject: Mersenne: error Hi, I've been using prime95 since sept. 1998 and never had any problems. Until yesterday I was testing an exponent in the 9.5 - 10 million range, but suddenly an error appeared while contacting the Primenet server (the exponent was almost finished +98%). I got the commen windows 95 error message: This program has performed an illegal operation and will be shut down. Details: PRIME95 caused an exception 6d9H in module KERNEL32.DLL at 0137:bff9a3c0.

I restarted my computer many times but it doesn't seem to make any difference. Any suggestions ?
